Billing forensics is the line-by-line audit of every utility invoice against the tariff under which it was issued, the meter data that produced it, and the operational reality of the facility. Errors are not rare. In a typical mid-sized commercial portfolio, we surface billing discrepancies on twelve to eighteen percent of invoices reviewed, with refund-eligible discrepancies averaging two to seven percent of annual spend.
- Catches estimated reads, duplicate charges, and franchise fee errors at scale
- Reconciles meter multipliers against nameplate specifications
- Audits budget billing and levelized billing settlements
- Files recovery claims with proper documentation for fast utility response

How this engagement runs
From first bill to documented savings
We connect to your utility accounts as an authorized agent and pull every bill, every interval read, every payment, and every adjustment for the past twenty-four to thirty-six months. We reconcile every line against the active tariff, the meter specifications, and the operational calendar. We document discrepancies with proof, file recovery claims with the utility, and track the refund pipeline through to settlement.

In depth
Common questions, answered
How often are utility bills actually wrong?
More often than facility managers assume. Our review of commercial accounts across BGE, PEPCO, Delmarva, and Washington Gas territory shows discrepancies on twelve to eighteen percent of invoices, with refund-eligible errors averaging two to seven percent of annual spend. The most common error categories are estimated reads billed as actuals, meter multiplier mismatches, franchise fee miscalculation, and duplicate or misapplied charges. These errors are not deliberate fraud; they are the byproduct of complex tariff structures, fragmented utility billing systems, and the simple absence of any party paying close attention. We are that party.
What is a meter multiplier and how does it get wrong?
Meter multipliers convert the raw count read off your physical meter into the kilowatt-hours and kilowatts billed on your invoice. On commercial demand meters, the multiplier reflects the ratio of the current transformers (CTs) and potential transformers (PTs) installed at the service entrance. A four hundred amp service with two hundred to five amp CTs has a multiplier of forty. If the utility billing system has the multiplier set to fifty, every kilowatt-hour you use is billed at one hundred twenty-five percent of actual, and you will overpay forever until someone reconciles it. We verify multipliers against the installed CT and PT nameplates as part of every engagement.
How long does refund recovery take after you find an error?
It depends on the error class and the utility. Estimated-read corrections typically settle in thirty to sixty days through a billing adjustment on the next cycle. Meter multiplier corrections require a service drop inspection and a true-up calculation; expect sixty to ninety days. Franchise fee corrections involve the municipality and can take ninety to one hundred eighty days. Tariff misclassification refunds, where statutes allow back-credit, are the longest at four to nine months because they often require formal complaint procedures. We track every claim through settlement and report status monthly until each dollar lands back in your account.
